Birefringence is a fundamental optical property for linear and nonlinear optical (NLO) materials. Thus far, it has proved to be very difficult to engineer large birefringence in optical crystals functioning in the UV region. Herein, we report the first 2D rare‐earth iodate–nitrate crystal Sc(IO3)2(NO3) (SINO), which is shown to exhibit giant optical anisotropy. Air‐stable SINO possesses a short UV absorption edge (298 nm), a strong NLO response (4.0 times that of benchmark KH2PO4) for the nitrate family, and the largest birefringence (Δn=0.348 at 546 nm) of inorganic oxide optical crystals. The unusually large birefringence and NLO response can be attributed to an optimized 2D layered structure, combined with highly polarizable and anisotropic building units [IO3]− and [NO3]−. These findings will facilitate the development of UV linear and NLO materials with giant optical anisotropy and promote their potential application in optoelectronic devices.

Deep‐ultraviolet nonlinear optical (DUV NLO) materials are attracting increasing attention because of their structural diversity and complexity. Using the two‐dimensional (2D) crystal structure prediction method combined with the first‐principles calculations, here we propose layered 18‐membered‐ring (18MR) boron oxide B2O3 polymorphs as high‐performance NLO materials. 18MR‐B2O3 with the AA and AB stackings are potential DUV NLO materials. The superior performing 18MR‐B2O3AB has an unprecedentedly high second harmonic generation coefficient of 1.63 pm V−1, the largest among the DUV NLO materials, three times larger than that of the advanced DUV NLO material KBe2BO3F2 and comparable to that of β‐BaB2O4. Its unusually large birefringence of 0.196 at 400 nm guarantees the phase‐matching wavelength λPM to reach this material's extreme absorption edge of ≈154 nm.

Over the last few decades, the development of each new nonlinear optical (NLO)-active functional unit has led to the discoveries of a series of excellent NLO materials. In the present work, based on first-principles studies, we identified a novel deep-UV (DUV) NLO-active functional unit, a non-pconjugated group viz. (NH 2 SO 3) À. By combining alkalineearth metals with (NH 2 SO 3) À group, two DUV transparent NLO sulfamates, M(NH 2 SO 3) 2 (M = Sr, Ba) with superior optical properties including strong SHG responses (1.2 and 2.7 KH 2 PO 4 (KDP)), short UV cutoff edge (< 190 nm) and moderate birefringence (0.056@589.3 nm for Sr(NH 2 SO 3) 2) were successfully synthesized. Our work has provided not only two promising DUV transparent NLO crystals, but also an innovative non-p-conjugated unit for developing more DUV transparent NLO materials. Nonlinear optical (NLO) crystals that can produce deepultraviolet (DUV) coherent lights (wavelengths shorter than 200 nm) have been extensively applied to photolithography, semiconductor manufacturing, atto-second pulse generation and advanced instrument development. [1-6] For a long period of time, the exploration of DUV NLO crystals was mainly focused on the p-conjugated systems, such as borates, [7] carbonates [7] and nitrates, [7] which resulted in some excellent DUV NLO materials including KBe 2 BO 3 F 2 , [8, 9] b-Rb 2 Al 2 B 2 O 7 , [10] NH 4 B 4 O 6 F, [11] MB 5 O 7 F 3 (M = Ca, Sr), [12, 13] ABCO 3 F (A = K, Rb; B = Mg, Ca, Sr) [14-16] and M 2 (NO 3)-(OH) 3 (M = Sr, Ba). [17, 18] In 2014, Chen et al. reported the first DUV NLO phosphate, Ba 3 P 3 O 10 X (X = Cl, Br), [19] which opened a new avenue to the development of non-p-con
